RAILWAY RAIL Filed April 14. 1932 Patented Sept. 4, 1934 Wm T rAranr orrica RAILWAY RAIL Gilbert Dudley Fish, Pelham, N. Y. Application April 14, 1932, Serial No. 605,183

3 Claims. '(01. 238- 150) I-Ieretofore railway rails have beenbattered and damaged at their ends with the result that they wear out first at the ends before they are otherwise Worn out and so have to be replaced.

The object of my invention is to provide an end for a rail which will last longer than heretofore, and so enable a rail to remain longer in service, when provided with my improvement.

This object is accomplished by my invention, some embodiments of which are hereinafter more particularly set forth.

For a more particular description of my invention, reference is to be had to the accom-' panying drawing, forming a part hereof, in which Figure l is a plan view of an end ofa rail embodying my. improvement;

Figure 2 is an end elevation of the same; Figure 3 is a side elevation of the same; Figures 4 to 7 inclusive show a modified structure, Fig. 4 being a plan View, 5 a sectional view taken on the line X--X of Figure 6, and Figure 7 is an isometric projection of the same.

Throughout the various views of the drawing, similar reference characters designate similar =5 parts. I

My invention is applied to an ordinary T rail 1, and relates to the head only, which is in contact with the Wheels of cars when in use.

2 is cut away at 3 at a diagonal plane, and in place of the removed material is put a hard steel end 4 which is supported by the material of a weld 5. The hard steel 4 ismuch harder than the material of the rest of the rail, and is preferably harder than the welding material 5.

The hard steel 4 is a very high class steel which is much better than that in the remainder of the rail, and it is made of a tough, hard, alloy steel. I

The rail when completed is finished so that the welded and added part exactly conform to the contour of the remainder of the head 2.

In the other embodiment of my invention herein shown, the insertion 6 is much larger than the block 4 and its outer surface conforms to that of the flange 2. It is provided with beveled surfaces 7, 8, and 9, so that the welding material 5 can be placed properly and securely with a perfect weld at all joints and no cracks. In

' this modification of my invention, the cut-out the welds joining the blocks to the rail shall'be of such form and depth as to restorethe continuity of the entire cut section of the rail, leaving no unwelded areas. This is because, regardless of any calculated stresses, the high intensity of pressure of wheels on the rail head, and the 69 severe impact at rail joints tend to start cracks in the rail head if there is any discontinuity of metal, no matter how strong the weld metal or how thorough the fusion.

It is also essential that the alloy steel used 6 for the stub end or block, 4 or 6, be considerably harder than the metal of which the rail is made and also that it be tough and highly resistant to shock. The weld metal must be at least as hard as the rail andpreferably somewhat harder, 3'0 but need not be so hard as the stub end.

On all exposed surfaces the welds are to be ground to a smooth finish with contours conforming accurately to the rail itself and the stub end.

Inasmuch as most battering of rails generally occurs at joints" where adjoining rail ends are slightly different in top elevation, it is believed thatthe hard blocks can be so adjusted before. I welding that the finished ends of all rails shall 88 have more nearly equal dimensions than rolled rails chosen at random. 7 In other words, it is expected that by adjusting the height of each block before it is weldedrin place, it will be possible to obtain the same effect as is sometimes accom 8 5" plished by laying ordinary rails in the order in which they come from the rolls at the mill.

The general object of the proposed invention is to provide rail ends of greater resistance to abrasion and deformation than the rails would other- 96 wise have, without any discontinuity ofgmetal and without any section which is in any way weaker than the original rail.

While I have shown and described some embodiments of my invention, it is obvious that it 9-5 is not restricted thereto, but that it is broad enough to cover all structures that come within end, a preformed block of metal of greater hardness than the body of the rail set into the space produced by the removal of the end part of the rail-end, the portions of the block located adjacent to the end of the rail being so shaped that they lie at an angle to the cut end of the rail, and weld metal filling the spaces between the block and rail, the block being formed to conform in cross-sectional shape to the body of the rail before being welded thereto.
